Reaction Steps
A solution of N-(methoxymethyl)-N-(phenylmethyl)-N-(trimethylsilyl)methylamine (0.50 g, 2.02 mmol) in CH2Cl2 (15 ml) was added drop wise, over a 30 minutes period, to a stirred solution of ((E)-2-nitro-vinyl)-benzene (0.30 g, 2.02 mmol) and trifluoroacetic acid (0.17 ml, 0.2 mmol) in CH2Cl2 (10 ml) at 0° C. The ice bath was removed, and the solution was stirred at 25° C. for an additional 48 h. It was then concentrated and purification by flash chromatography (SiO2, EtOAc/H 1:6) afforded 0.38 g (68%) of the title compound as a colorless oil. ES-MS m/e: 283 (M+H+).
